Abstract: Static vertical loading tests and stress tests of four types of piles, that is, the normal cast-in-place pile, the cast-in-place pile with post-grouting, the cast-in-place pile with expanded-base, the cast-in-place pile with expanded-base and post-grouting, are performed in the same site. Based on the field experiments, compares the bearing capacity behavior, the distribution of axial force and lateral friction of the four types of piles. And transmission rule of axial force and the action of lateral friction of the piles is analyzed. The results of researches prove that the cast-in-place piles with expanded-base and post-grouting possess the characteristics of low settlement and high bearing capacity.

Key words: cast-in-place pile with expanded-base and post-grouting, expanded-base, post-grouting, transmission of axial force, action of lateral friction
